Alan Hook has two problems in his life: his jovial but infuriating father Brian, and his son Vincent. In this episode it's Vincent's 18th Birthday.

Alan thinks Brian is drinking too much, but in his efforts to help the situation, Alan ends up in trouble with the police.

Beryl agrees that Vincent can have a party in the house, leaving Alan with no alternative but to spend a restful evening at his father's place.

Alan discovers, to his horror, that Beryl has given Brian the task of arranging a holiday for them all. But it couldn't be worse than the family holidays he remembers—could it?

Alan's father re-enters Alan's life due to a recent bout of illness. Alan then goes through a style crisis made worse when his dad takes him to Mr Nigel's shop.

While Alan bemoans the lack of discipline in society, Beryl makes an exciting discovery about Vincent. Brian has a secret in his past that affects them all.
